Draw the image of △ABC under a dilation whose center is P and scale factor is 1/2
Vesna [10]

Answer:

Step-by-step explanation:

Let the point P is at the origin (0, 0).

Then the coordinates of A, B and C will be (8, 4), (-2, 2) and (4, -4) respectively.

Rule for the dilation of a point by a scale factor = k

(x, y) → (kx, ky)

If k = \frac{1}{2}

Then, A(8, 4) → A'(4, 2)

          B(-2, 2) → B'(-1, 1)

         C(4, -4) → C'(2, -2)

Now we can plot the new image with points A', B' and C'

NNADVOKAT [17]

Answer: Fraction of paint used for bird  house = \dfrac14

Step-by-step explanation:

Let quantity of the total paint be 1.

Given:  Fraction of paint to book shelf = \dfrac38

Fraction of Paint to leg = \dfrac14

Fraction of Paint left = \dfrac18

Let x= fraction of paint used for bird house.

Total paint = \dfrac38 +\dfrac 14+\dfrac18+x=1

\Rightarrow\ \dfrac{3+2+1}{8}+x=1\\\\\Rightarrow\ \dfrac{6}{8}+x=1\\\\\Rightarrow\ x=1-\dfrac68\\\\\Rightarrow\ x=\dfrac{2}{8}=\dfrac14

So, Fraction of paint used for bird  house = \dfrac14
